Such lengths of trunking generally have a base component and a cover component, the base having longitudinal dividing walls such that when the cover is fitted a plurality of ducts are formed through which services may pass.
  • the lengths of trunking may be arranged to have a plurality of longitudinal ducts separated from each other by the longitudinal dividing walls.
  • Figure 1 is a transverse section of a typical length of trunking 10 mounted to a mounting surface 12.
  • the trunking 10 comprises a base component 14 and a cover component 16, with the cover 16 shown in an exploded relationship relative to the base 14.

  • Such electrical wiring accessories may comprise electric sockets or data terminals, for example.

  • the mounting box 40 is incorrectly positioned in a longitudinal direction when the aperture 54 is formed, it may be necessary to form a second aperture in order to correctly position the mounting box 40 within the trunking 10. Again, this may slow down the installation process.
  • a length of trunking is often oriented horizontally along a vertical wall of a room, as shown in Figure 1.
  • an installer will place cables along an open duct of the base 14. He will then make any necessary connections and complete the installation by fitting the cover 16.

  • the mounting box 150 further comprises opposing side walls 156 and 158 extending rearwardly of the frame 152.
  • the back face of the mounting box 150 is substantially open.
  • the boxlike enclosure has a front face defined by frame 152, side faces defined by opposing side walls 156 and 158, top and bottom faces defined by the longitudinal walls 114 and 116 respectively, and a back face defined by the base 112.
  • the boxlike enclosure satisfies standards such as
  • the frame 152 is positioned closer to the base 112 and to the wall than in prior art trunking systems whilst maintaining a constant volume within a box of similar front dimensions. Therefore, a trunking system comprising the length of trunking 110 and the mounting box 150 protrudes less from the mounting surface than prior art trunking systems and mounting boxes. Additionally, the substantially open back face of the mounting box 150 enables cables to be passed from the wall directly into the mounting box 150 in the central duct 122 without the need to drill through the back of the mounting box 150. Thus, only the base 112 of the length of trunking 110 and the wall require drilling, and the mounting box 150 may be positioned subsequent to the drilling.
  • the frame 152 and the aperture 154 are substantially rectangular in shape.

  • the first sides 160 and 162 of the frame 150 comprise flanges 176 and flexible catches 178 adapted to engage the engagement members 136 and 140 of the length of trunking 110. Nonetheless, the mounting box 150 is free to slide longitudinally with respect to the length of trunking 110. In use, an installer may slide the mounting box 150 to a longitudinal position of his choice within the length of trunking 110.
  • the size and spacing of the knockouts 126 is such that a pair of knockouts 126 will be located at least partially above and below a standard sized two-gang mounting box 150 for any longitudinal position of the mounting box 150. In Figure 5, the mounting box 150 is positioned directly between a pair of knockouts 126.
  • the installer may remove either the top knockout 126 in the longitudinal wall 114 above the mounting box 150 or the bottom knockout 126 in the longitudinal wall 116 below the mounting box 150. If the installer removes the top knockout 126 to form an aperture, -he may then easily pass power cables, for example, from the top duct 118 through the aperture and into the mounting box 150 in the central duct 122 without the need for drilling. This is possible because the mounting box 150 comprises a substantially open top face. In this configuration, the power cables are still isolated from any data cables in the bottom duct 120 by virtue of the longitudinal wall 116 and the bottom knockout 126 which has not been removed. Thus, a trunking system comprising the length of trunking 110 and the mounting box 150 does not restrict the longitudinal positioning of a mounting box by the forming of holes in the top or bottom face of the box.

In this position, forward surfaces 190 of the catches 178 engage with backward surfaces 192 of the first portion 182 of the engagement members 136 and 140. This prevents the mounting box 150 from falling out of the central duct 122. In use, as the mounting box 150 is inserted into the central duct 122, the flexible catches 178 flex inwards to enable the flexible catches 178 to move past the engagement members 136 and 140.

  • the removal of one or more side walls 156 and/or 158 enables a plurality of mounting boxes 150 to be placed adjacent to one another spaced by socket spacers in the central duct 122. In this way, a bigger mounting box is effectively formed since cables may be passed from one mounting box to an adjacent mounting box via the aperture formed by removing the inner side walls without compromising cable separation.

  • the mounting box may be oriented so that the side wall 357 abuts the top longitudinal wall 114 or the bottom longitudinal wall 116.
  • An advantage of this embodiment is that the side wall 357 further insulates and strengthens the mounting box 350.

Abstract

La présente invention décrit un dispositif de montage (150) destiné à être utilisé dans un système d’acheminement de câbles. Le dispositif de montage comprend un cadre (152) comportant des bords et une ouverture (154) qui, durant l’utilisation, définit une face avant du dispositif de montage et est adaptée pour recevoir une plaque de socle. Le dispositif de montage comprend en outre des parois latérales opposées (156, 158) qui comportent des bords et qui s’étendent vers l’arrière du cadre. Les bords du cadre et parois latérales définissent sensiblement un parallélépipède rectangulaire comportant une face arrière sensiblement ouverte. Un autre dispositif de montage destiné à être utilisé dans un système d’acheminement de câbles ; un système d’acheminement de câbles comprenant une unité de base et un couvercle détachable ; et un système d’acheminement de câbles en association avec un dispositif de montage sont également décrits.
